Failure with data providers

👋 

If a failing test uses data providers, such an error would occur:

```php
-previous: ReflectionException {#4506
      #message: "Method testListAction with data set #foo does not exist"
      #code: 0
      #file: "./vendor/mheap/phpunit-github-actions-printer/src/Printer7.php"
      #line: 98
```

because `\PHPUnit\Framework\TestFailure::getTestName` includes the data set name.
